I am new to RVM and looking to use it as I deploy my Rails app to a Digital Ocean server. I am following this tutorial and trying to get my Mina script to run (similar to Capistrano). The script includes a set up section with these lines:
source /etc/profile.d/rvm.sh
rvm use || exit 1
Unfortunately, rvm.sh does not exist in /etc/profile.d (or anywhere else on my server). rvm seems to be installed just fine (I can set list rubies, set my Ruby default version, etc). I'm not even sure what rvm.sh would contain if it existed.
Thanks in advance for any help or suggestions you can provide.
#mpapis got me on the right path here. I had installed rvm under one user, but not for this user. I wound up uninstalling rvm and starting from scratch, installing rvm for multiple users.

I am trying to install jekyll.
I run gem install bundler jekyll
After installing gems I run bundle init and get
bash: bundle: command not found
How can I fix it?
You can get a gem's directory using gem which. For example:
$ gem which jekyll
/home/username/.rvm/gems/ruby-2.6.4/gems/jekyll-4.0.0/lib/jekyll.rb
Then append the directory to your PATH:
$ export PATH="$PATH:/home/username/.rvm/gems/ruby-2.6.4:"
The reason why you are getting "command not found" after installing gems is because they were installed in a location that your bash shell does not yet know about. The way the computer looks up commands is by looking at the PATH, which is a list of folders where the computer should look for commands, such as bundle. The previous answer is on the right track, but unfortunately, the gem which command will only tell you about locations that are already in your PATH, which might not include the folder where bundler and jekyll were installed.
The location of the gems depends on how you installed Ruby, so without knowing that, I can't tell you what to put in your PATH. What I can tell you is that what you are experiencing is unfortunately very common, but there is a fix. To avoid needless frustration and to help people like you, I wrote a script that will automatically set up a proper Ruby environment for you, including updating your PATH and everything else that is necessary to be able to install gems and use them right away without getting any errors. Check out the links at the bottom of this answer to learn more about my script.
In the meantime, I can make some guesses and see if I can help. If you installed Ruby with Homebrew, then this should fix it:
Run this command:
echo 'export PATH="/usr/local/opt/ruby/bin:/usr/local/lib/ruby/gems/2.7.0/bin:$PATH"' >> ~/.bash_profile
And then quit and restart your terminal. Now you should be able to run bundle init.
If you are reading this and you are not the original poster, you might need to replace .bash_profile in the command above with .zshrc depending on which shell you are using. You can tell by looking at the error. If you are using zsh, it will say zsh: bundle: command not found.

ok, so i'm coming from a python virtualenv environment, so please bear with me...
i am trying to install rvm on a non-internet visible machine (ie it doesn't have direct outside access). so
curl -L https://get.rvm.io | bash -s stable --ruby
would not work. no problems i thought, i'll just copy the file over from another machine and do a cat that worked, however, because rvm tries to download the source files directly from the web, it again failed....
so i found that if i put the tarballs under ~/.rvm/archives, i can install rvm as a single user (and take up ~200MB of my home space)... however, i want to install for multiuser for production purposes and use .rvm directories in my project. however, my /usr/local is read only (afs mount).... so rvm fails again.
any ideas? i don't particularly like the idea of having a rvm user and group.
I believe you can supply --path=/opt/rvm to the RVM install script to change the location of a multi-user installation.
I don't believe the RVM group can be changed as it relies on that group to operate correctly.
hmm... so i decided to look at the rvm-install script (ie https://get.rvm.io). basically, it was hardcoded to /usr/local/rvm, so i just changed that to /opt/rvm.
i then also had to add a check for the rvm tarball under the get_and_unpack function:
if [ -e ${rvm_archives_path}/${_file} ]
then
true
elif curl -L ${_url} -o ${rvm_archives_path}/${_file}
then download the file at https://github.com/wayneeseguin/rvm/tarball/master into /opt/rvm/archives/wayneeseguin-rvm-master.tgz
that installed rvm fine into /opt/rvm.
however, logging back in will result in -bash: __rvm_add_to_path: command not found. this is because the profile.d script is hard coded to /usr/local/, so doing a find and replace on /etc/profile.d/rvm.sh to /opt/ did the trick.
however, all the files are still group'd to rvm. which is fine, but another group i have to justify to my unix-admin.
I have RVM installed, with project rvmrc files enabled.
In my bashrc I have:
rvm use 1.9.2
However, in one of my project rvmrc files I have:
rvm use 1.8.7
Which works great, however if I open up a new terminal window within the project I get:
Using /home/.../.rvm/gems/ruby-1.8.7-p352
Using /home/.../.rvm/gems/ruby-1.9.2-p290
Obviously, I want to 1.8.7, but the bashrc gets run after the project rvmrc. Meaning I'm using the wrong rvm so either have to cd out and back into the directory or run rvm use 1.8.7 again.
Is there anyway to force the rvmrc file to run after the bashrc?
I know about rvm default, but not sure if I want to\can use this.
please read this: https://rvm.beginrescueend.com/support/faq/#shell_login it describes which files should be used in which use cases.
as for rvm --default 1.9.2 it should be used over manually entering version into your rc file as it is loading ruby only if one was not yet selected.
Simplest solution for your rc files problem (I guess you have one) would be rvm get head --auto which will reorganize sourcing rvm in your rc files - to make it fully functional you need to restart your graphical session (or just reboot computer).
I'm on Mac OSX Snow Leopard. I tried to post a similar question to the RVM Google group but it did not seem to get posted.
I'm worried that I've done something fundamentally wrong with my RVM install that's causing these errors, that seems to be related to paths, at each step of the way. Have any of you seen this behavior before?
I started to teach myself Rails programming as of about two months ago with a working environment of Ruby 1.9.1 and Rails 3.0.3, based on a hivelogic install tutorial that had me modify my ~/.profile file and install the relevant bits to ~/usr/local/src/. For reference, the line in my ~/.profile file was this when I installed RVM, if that makes any difference:
export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/usr/local/src:$PATH"
In my terminal I installed RVM as a user using the standard user github bash script.
I tried to install Ruby 1.9.2, which kept running into a weird error about a libfile somewhere. After much Googling I found someone on Stack Overflow that recommended renaming the ~/usr/local directory while performing the Ruby install -- I did this, and the install complete.
Then I did gem install rails and tried to do bundle install in my app, which gave an error when trying to install the SQLite3 gem (even though I already had SQLite3 installed and working). Again, I spent a day Googling this and eventually found "Unable to install sqlite3-ruby gem" that said if I used Macports to sudo port install sqlite3 it would work.
I tried that from the base directory, and Macports did its thing but it didn't fix the problem. Then I did the same thing from my app directory and it fixed the SQLite3 error I was getting.
Now I am able to run rails server and rails generate again, which is great, but then I tried to "annotate" my new model, and I get this error: http://pastie.org/1481570
I have not yet solved this issue, and have looked at many threads of similar issues. This, for example, did not solve my problem: https://github.com/james2m/annotate_models/commit/5997da9692c9b222e8d1be22dfad6ed8638c16a1
I even tried copying my source code directly into the rvm/user/ directory in case that relative path was causing problems, but it doesn't seem to have fixed anything. Maybe I need to uninstall RVM and re-install it as root instead of a user-level thing?
What do you think is the best way to get annotate to work and hopefully get RVM to play nice with my gems going forward?
I'm unfortunately REALLY new to terminal, code, etc, so any help would be much appreciated.
On Snow Leopard you should modify either ~/.bashrc or ~/.bash_profile, preferably the later. Also, RVM will not need anything in ~/usr/local since it's entirely self-contained in ~/.rvm.
RVM uses a nice little shell function to sense the needed directories and desired default Ruby. I suspect either the instructions you followed were very out of date, or poor recommendations. The current RVM installation requests you add:
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # This loads RVM into a shell session.
to your ~/.bash_profile
The RVM site has lots of troubleshooting tips for things like MySQL. I'd strongly recommend backing out of the things those other tutorials had you do, and refer to the instructions on RVM's site. It is very easy to get things working right if you do it the RVM-way.
Download and install Apple's latest version of XCode from their Developer site if you haven't already. There have been some broken versions shipped on the DVDs.
Install. In particular follow the "Post Installation" section.
Following that, do whatever rvm notes says to do as far as libraries. Following that, you should be able to use rvm info to gather useful info about your installation. It is your best friend.
Database integration will point you to how to fix MySQL's wagon.
RVM development happens fast. Keep it updated, at least once a week using rvm get head.
At that point you should be in a good place to start reinstalling gems.
I'm on a Mac running 10.6.4 Snow Leopard, and apparently ruby comes ready to go. But I'm new to Ruby, trying to learn the Rails framework, and so i decided to install the latest version 1.9.2. I followed the instructions here, but after I compile and install, when I run ruby -v I'm still getting 1.8.7. Anyone can help a noob out?
When I use which ruby I am getting usr/local/bin/ruby, so the path has changed and is correct.
UPDATE:
It seems I was having issues because I was using two login files to set my path (.bash_login and .profile). You can only use one, and the first one that exists and is readable will be used. I eventually switched to RVM and used .bash_login to load RVM into shell.
Well, the sw isn't lying to you. So something is not as you expect.
Try /usr/local/bin/ruby -v and see what version it is.
Added: Also, try locate ruby|more to see where the ruby files are on your system.
You may need to change your path to use your newly installed copy of ruby.
Added more: did you add the Path to your ~/.profile file as the instructions tell you to do in step 1?
Did you restart your terminal session after changing the ~/.profile file? (Quit and restart terminal.)
